This invention pertains to a brewing head assembly of a coffee machine that enables easy insertion and removal of the filter as well as locking of the filter and the filter holder into the brewing head to form a water-tight seal under pressure. The filter holder can be inserted into the brewing head assembly by sliding the filter holder into the brewing head assembly from the front, top, or side or by swinging the filter holder, which may be pivotally-attached to the brewing head assembly, into the coffee machine. The locking mechanism for inserting and securing the filter holder to the brewing head assembly may be motor-driven. Additionally, the motorized method for opening/closing and locking/unlocking the brewing head assembly may be operated by remote control. Furthermore, the boiler or heating system is may be maintained separately from the brewing head assembly.
